SPRING-CLIP FOR PNEUMATIC HAMMERS.

To all whom it may concern: I

Be it known that I, J osnrn F. EISCHEID, a citizen of the United States, residing at Plattsmouth, in the county of Cass, State of Nebraska, have invented certain new and useful Improvements in Spring-Clips for Pneumatic Hammers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spring clips for pneumatic hammers.

The object of the invention resides in the provision of an improved form of clip for securing rivet set heads'in operative relation to pneumatic hammers.

In describing the invention in detail reference will be had tothe accompanying drawings wherein like characters of refer ence denote corresponding parts in the several views, and in which- Figure 1 is a side elevation partly in section of a pneumatic hammer having the improved clip associated therewith. Fig. 2, an enlarged end view of the spring-clip which secures the head of the set to the hammer in operative relation to the shank, and Fig. 3, a section on'the line 3 3 of Fig. 2.

Referring to the drawing, A indicates'a pneumatic hammer of well known construction and which includes the usual tubular body 10 wherein is slidably mounted a plunger or piston 11 adapted to be reciprocated through the medium of compressed air in the usual and well known manner. The tubular body 10 is provided adjacent its tool receiving end and exteriorly thereof with a circumscribing groove 12. Engaged over the tool end of the body 10 is a spring clip B. This spring clip is in the form of an open ring-like body tapered longitudinally and having a segmental portion removed there- Specification of Letters Patent.

from as at 13 so as to permit said clip to expand and contract readily. The major end of the clip B is provided with an inwardly directed flange 14 which is adapted to engage inthe groove 12 to secure the clip to the body 10, while the'minor end of said clip is flared as at 15 to permit the ready insertion of the shank and head of the set. The shank of the set is indicated at 16 and is inserted in the body 10 as shown. This shank is provided adjacent its outer endwith a circumscribing flange 17 adapted to engage the end of the body 10 and limit the movement of the shank inwardly of said body. The head-of the set is indicated at 18 and has the inner end thereof provided-with an outwardly directed flange 19 and a centrally disposed recess 20, the latter receiving the outer end of the shank 16, while the clip B engages over the flange 19 and in that .manner firmly secures the head 18 against disengagement from the shank. The outer end of the head 18 is provided with a recess 21 of a shape suitable for the purpose for which it is intended.

The structure, heretofore described is not only useful in securing rivet set heads to a pneumatic hammer but also in securing various other tools to the hammer.

What I claim is A spring clip for pneumatic hammers formed of a tapering tubular body having a portion of its wall removed throughout its entire length and its minor end flared, and a flange on the major end of the clip for engagement in a groove in the pneumatic hammer body. In testimony whereof, I, afiix my signature, in the presence of two witnesses.
